Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4172701XX-3 is determined by the following critical parameters:

Physical Compatibility: Identical board dimensions (4.2" L x 3.6" W / 107mm x 92mm) ensure mechanical fit within existing enclosures and mounting structures.

Interface Compatibility: RS-232 serial communication protocol must be maintained for system integration without firmware or hardware modifications.

Voltage Compatibility: Substitute parts must support the required input voltage (12V) and provide at minimum the output voltages needed by the system (3.3V, 5V, 12V).

Functional Equivalence: Both substitute parts (4176400XX-3 and 4176401XX-3) are active LCD driver/controller boards from the same manufacturer, designed for identical display sizes and communication protocols.

The substitute parts 4176400XX-3 (ALT-1920 series) and 4176401XX-3 (HLT-1920 series) meet all substitution criteria through identical physical dimensions, matching RS-232 interface, compatible input/output voltage specifications, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Digital View Inc. and maintain ROHS3 compliance and MSL-1 ratings identical to the original component. The 4176400XX-3 (ALT-1920) and 4176401XX-3 (HLT-1920) are active products with current manufacturing support, eliminating obsolescence risk associated with the 4172701XX-3.

The substitute parts provide expanded input voltage capability (12V and 24V support) and additional output voltage options (18V), offering enhanced system flexibility while maintaining backward compatibility with existing 12V input and 3.3V/5V/12V output requirements.

Operating temperature range differs between the original (-40°C ~ 80°C) and substitutes (0°C ~ 60°C). Applications requiring extended temperature operation below 0°C or above 60°C must evaluate environmental conditions against substitute specifications.

Frequently Asked Questions (FAQ)

Q: Can 4176400XX-3 or 4176401XX-3 directly replace 4172701XX-3 in existing systems?

A: Yes, both substitute parts are direct replacements. Identical physical dimensions, RS-232 interface, and compatible voltage specifications (12V input, 3.3V/5V/12V output) ensure mechanical and electrical compatibility without system modifications.

Q: What is the difference between ALT-1920 (4176400XX-3) and HLT-1920 (4176401XX-3) series?

A: Both parts share identical electrical specifications, physical dimensions, interface protocols, and compliance certifications. The series designation reflects internal design variants. Selection between the two is interchangeable from an engineering compatibility standpoint.

Q: Does the expanded input voltage range (12V, 24V) on substitute parts affect 12V-only systems?

A: No. The substitute parts accept both 12V and 24V input. Systems operating at 12V will function identically to the original component. The additional 24V capability provides future flexibility without impacting existing 12V implementations.

Q: Are there temperature range limitations when substituting?

A: The substitute parts operate within 0°C ~ 60°C, compared to the original -40°C ~ 80°C range. Applications requiring operation below 0°C or above 60°C must confirm environmental conditions are within substitute specifications.

Q: What is the inventory status for substitute parts?

A: 4176400XX-3 (ALT-1920) has 1027 pieces in stock. 4176401XX-3 (HLT-1920) has 746 pieces in stock. Both are active products with ongoing manufacturing availability.

Q: Are compliance certifications maintained with substitute parts?

A: Yes. Both substitute parts maintain ROHS3 compliance, MSL-1 rating, and REACH unaffected status identical to the original 4172701XX-3.
